Leaf-miner:
Mine linear, long, frequently doubling back, initially on the underside,
later chiefly on upper surface; frass in discrete grains; forming
a loose string initially, later more irregular. Pupation in the
mine (Godfray, 1985).
Larva: The larvae of flies are leg-less maggots without a head capsule (see examples). They never have thoracic or abdominal legs. They do not have chewing mouthparts, although they do have a characteristic cephalo-pharyngeal skeleton (see examples), usually visible internally through the body wall.
Puparium: The puparia of flies are formed within the hardened last larval skin or puparium and as a result sheaths enclosing head appendages, wings and legs are not visible externally (see examples).
White; posterior spiracles each with about 7 bulbs.
